Express Static Directory over HTTPS - node.js

Question

I would like to implement Node.js with Express for static content over HTTPS. Scouring the Web reveals tons of examples of Express with HTTPS and tons of examples of Express serving a static directory, but I cannot find an example using all three Express, HTTPS and static.
Moreover, looking at the examples I can find, I cannot piece together how to accomplish this.
Here is what I have found:
Express Static Directory over HTTP
var fs = require('fs')
var app = require("express");
var server = app();
server.use(app.static(staticDir))
server.listen(webPort)
Express over HTTPS (without Static Directory)
const app = require('express')();
const https = require('https');
const server = https.createServer(
{
key: fs.readFileSync('server.key'),
cert: fs.readFileSync('server.cert')
},
app
);
server.listen(APIPort);
When I try combining the two approaches, I get stuck because the static example bypasses createServer, and yet createServer is the crux of getting to HTTPS in the examples.
I'm sure the answer is simple, but I cannot arrive at or locate the solution.

Answer 1

Could you try the below code-snippet and see if it works for you?
const fs = require('fs');
const https = require('https');
const express = require('express');
const app = express();
app.use(express.static(process.env.SERVE_DIRECTORY));
app.get('/', function(req, res) {
return res.end('Serving static files!');
});
const key = fs.readFileSync(__dirname + '/selfsigned.key');
const cert = fs.readFileSync(__dirname + '/selfsigned.crt');
const options = {
key: key,
cert: cert
};
const server = https.createServer(options, app);
server.listen(PORT, () => {
console.log(`Serving on port ${PORT}`);
});
Please make sure to do the suitable changes before running the above code.
